- Martina Meijer taught a New York City summer school class during a 100°F July Fourth weekend with a malfunctioning AC and no scheduled activities; school officials told her to stay inside and follow YouTube "brain breaks" because outdoor weather was too hazardous for recess.
- Philadelphia School District dismissed students early from 52 insufficiently air-conditioned schools on the last day of school in early June, with Superintendent Tony Watlington Sr. saying the district either sends students home or moves schools to virtual days once temperatures climb above 85-90°F.
- Madison Metropolitan School District in Wisconsin canceled elementary summer school when heat index projections reached 108°F, designating gyms and libraries as "cooling centers" equipped with hydration stations and cooling towels.
- Canadian wildfire smoke in mid-July forced New York City's Summer Rising program to move all outdoor activities indoors for thousands of students, eliminating the recess that researchers say improves academic outcomes and emotional regulation.
- A 2021 Center for Climate Integrity study found over 13,000 US public schools would require $40 billion to install HVAC systems; Philadelphia's school buildings average 73 years old and cannot accommodate simple window-unit retrofits, Watlington said.
- Federal regulations that would mandate water breaks, rest periods, and cooling areas to protect workers including teachers from heat illnesses have stalled for the foreseeable future, leaving safety protocols to ad hoc staff judgment.
- Children are especially vulnerable to heat-related illness because their thermal regulation systems are still developing and they sweat less, according to Elizabeth Bechard of Moms Clean Air Force — and students who lack air-conditioning at home have no chance for their bodies to rest and recover.
Why it matters: The students who most need summer school — those with academic challenges — are the same ones being asked to catch up in overheated classrooms where cognition is impaired and AC is failing, widening the achievement gap precisely when it should narrow. A $40 billion HVAC retrofit bill hangs over 13,000 schools while federal heat-safety standards remain stalled, leaving individual teachers to improvise life-and-death decisions.
